Winehouse, 23, and Fielder-Civil, 23, a gofer for music videos, have spent a romantic three days at The Shore Club hotel on South Beach, where since Wednesday they've been seen kissing and holding hands.

They had been engaged since April after he proposed to her with a diamond ring from Tiffany. At the time, Winehouse told U.K. newspaper The Sun, "I hope to be with him for the rest of my life." But the couple had not announced a wedding date.

In fact, the pair has shared a tumultuous, on-and-off relationship. Though they started dating two and a half years ago, they split up for some time. That period inspired Winehouse to write "Tears Dry On Their Own" from her new album Back to Black.

Lately, though, the singer has been nothing short of effusive about her relationship. In a recent interview with Entertainment Weekly she said, "We've been back together about a month, but we've been seeing a lot of each other for quite a few months." Added Winehouse: "We are best friends."
